The "Ghostbusters" sign is the international symbol (International Organization for Standardization or ISO) for NO. As with many early MyFord Touch issues, you can look in the owners manual, find the fuse location in the fuse panel under the glovebox, pull that fuse for a minute or so, reinsert the fuse and allow the system to reboot. There should be a red fuse puller attached to the inside top of the fuse panel under the hood, or lightly grab the fuse with a needle nose pliers. You will lose all your saved data, that may solve your problem. Another option is to take your car to the dealership and have the system checked under warranty.
